A signal generator generates either audio or RF frequencies (depending on the capabilities and designed purpose of the generator) for testing other electronics equipment. Makes it easier to make tests on a device without having to have it "in circuit". It's a lot easier to test a piece of equipment on a work bench rather than trying to test it in place.A function generator supplies TTL (transistor to transistor) square wave pulses, sine and sawtooth wave forms for various testing purposes. It's a lot easier to work on something on the work bench and being able to remove a circuit board and just supply power and a signal saves having to take a whole piece of equipment into the shop. Then again, you also can use an oscilloscope for troubleshooting when you jave a good, known signal to work with. That applies to both types of generators.A: A function generator is just like a signal generator except it generates a function like a ladder step or unusual increases or decreases in voltage to generate a required function
You would use a Frequency Generator to generate tones. They can also be refered to as a Function Generator or Signal Generator. Check out this page on wiki for more information. http://en.wikipedia.org/wiki/Signal_generator
To test a coaxial cable for proper functioning, you can use a cable tester or multimeter to check for continuity and signal strength. Connect the cable to the tester and check for any breaks or shorts in the wiring. You can also use a signal generator to send a signal through the cable and check for any interference or loss of signal.

To trace a problem in an amplifier. Send in a signal and trace its' path.
To test a coax cable, you can use a cable tester or a multimeter to check for continuity and signal strength. Connect the cable to the tester and check for any breaks or shorts in the wiring. You can also use a signal generator to send a signal through the cable and check if it is received properly at the other end.
You can use a PNP or an NPN transistor in a fire alarm circuit. Both will work. It all depends on how you want to energize the alarm, and with what polarity of signal.
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.
Hp signal generator serves as a wireless broadcaster. The engineers designed this instrument. It was designed to be used in RF applications exclusively 50 omega loads.
To set up a signal generator, first connect it to the desired output device or circuit using appropriate cables. Next, power on the generator and select the desired frequency, waveform type, and amplitude settings. To calibrate, use an oscilloscope to measure the output signal and adjust the amplitude and frequency settings on the signal generator until the desired specifications are met. Finally, verify the signal integrity and consistency across the intended operating range.
Because two diodes is not a transistor. There is an interaction between the junctions in the transistor, because of their proximity, that you don't get in the two diodes. The only use of modeling a transistor as two diodes back to back is to test a transistor with a multimeter as a quick go-nogo test for basic operability.
A function generator is a piece of electronic test equipment. Its main use is to generate electrical waveforms.
